Gefahrenhinweise
Hazards Summary
Emergency treatment: Plants- pyrrolizidine alkaloids; Pyrrolizidine alkaloids (PAs) cause veno-occlusive liver disease. Diagnosis is difficult because symptoms may be delayed for days or weeks. After drinking herbal tea or eating plants contaminated with seeds of PA plants, symptoms may include vomiting, abdominal pain, hepatomegaly, and later cirrhosis and ascites. Jaundice may be present. Children may appear to have Reye's syndrome. [HSDB] Plants containing significant amounts of pyrrolizidine alkaloids are found all over the world, comprising about 3% of all flowering plants. They have long been known to be toxic to livestock. Outbreaks of poisoning cases in humans after food contamination have been reported, and the problem is endemic in some central Asian republics. [Reference #1] Teas containing PAs include coltsfoot, comfrey, gordolobo, groundsel, mate, tansy ragwort, and T'u-san-chi. The teas may be prescribed as herbal remedies for anxiety or amenorrhea. The alkaloid is concentrated in the root of the plants. As little as 85 mg may be toxic. [Haddad, p. 1082] Over 6000 plants produce pyyrolizidine alkaloids, some of which are toxic. This is probably the most common plant toxin, and it affects livestock, wildlife, and humans. [Haddad, p. 494] Mechanism of toxicity is the metabolic conversion into pyrroles that act as alkylating agents. Hepatic disease leads to cirrhosis and possibly increased risk for hepatic carcinoma. Most poisoning cases have resulted from contamination of food grain with the seeds containing the alkaloid or from medicinal herbs. An estimated 20% of patients die, 50% recover completely, and 30% develop chronic hepatic veno-occlusive disease. [Goldfrank, p. 647, 1546]
Atmospheric Standards
Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Xylenes is included on this list.
